WARNING !
Only authorized personnel should perform inspection or maintenance
and service procedures. Unauthorized personnel attempting these
procedures do so at the risk of personal injury or death.
DANGER !
Failure to properly adhere to lift blocking procedures is to risk the
sudden and uncontrolled descent of the lift during maintenance or
inspection. A falling lift can cause severe injury or death.
This procedure describes the only factory-approved method of working under a lift.
Follow these instructions EVERY time you plan to reach or crawl beneath the lift to
perform service or maintenance – no matter how momentary that might be.
If the factory-provided maintenance devices are damaged or missing, stop immediately
and consult the factory for assistance. The manufacturer is not liable for your failure to
use the approved maintenance devices and procedures that have been provided.
1. All load must be removed from the lift prior to engaging the maintenance devices.
These devices are designed to support an unloaded lift only. Failure to remove
the load from the lift prior to blocking could cause the failure of the maintenance
devices and allow the lift to fall unexpectedly. This can result in personal injury
or death, or permanent damage to the maintenance devices and/or the lift.
2. Raise the lift to its fully raised position. If you do not, the maintenance devices
may not be able to be placed properly in their designed blocking position.
3. Locate both hinged maintenance locks permanently welded outside the base
frame on the roller end of the lift base legs. Both locks must be flipped over and
resting inside the base frame and thus in the roller path of the lift (See Figure 7).
4. Lower the lift platform until the leg rollers make contact with both maintenance
locks. Re-check to ensure that both devices are fully and properly engaged with
the leg rollers. If both left and right maintenance locks are not fully engaged the
lift could fall unexpectedly, resulting in permanent damage to the devices or the
lift.
